問題描述

我的活動中有一個警報對話框，不希望用戶通過單擊對話框外部來關閉它.根據我的研究(like this)，我發現了 setCanceledOnTouchOutside(false); 方法.但是，我無法在我的應用程序中使用它，并且可以在使用此方法時關閉對話框.

I have an alert dialog in my activity and don't want user can dismiss it by clicking outside of the dialog. Based on my research (like this) I found setCanceledOnTouchOutside(false); method. However, I couldn't use it in my application and it is possible to dismiss dialog while I have this method.

這是我的代碼:

private AlertDialog alertDialog;
alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setCanceledOnTouchOutside(false);
alertDialog.setTitle("");
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
        switch (intAlertAction) {
            case 1:
            case 2:
            case 3:
            default:
        }
}
});

任何建議將不勝感激.

推薦答案

這是一個有趣的問題，我想我知道你的答案.

This is an interesting question and I think I know your answer.

我一直在不同平臺上測試應用程序，我注意到它們之間存在細微差別.在 android 4.0 以上，當您觸摸 Toast 消息時，它就會消失.我想對話框(和 AlertDialogs)也是如此.觸摸時它只是消失"(但它不會消失！-只是看不到).

I have been testing an application on different platforms and I noticed a small difference between them. Above android 4.0 when you touch a Toast message, it simply disappears. I guess it is the same with dialogs (and AlertDialogs). It simply "disappears" when touching (but it is not dismissed! - just cannot be seen).

希望對您有所幫助！
